SAW-SETTING DEVICE.

To all whom it may concern.

Be it known that I, ALLEN S. HARRIS, a citizen of the United States,residing at Rich Hill, in the county of Knox and State of Ohio, haveinvented new and useful Improvements in Saw-Setting Devices, of

- which the following is a specification.

This invention relates to saw setting de vices for the purpose ofsetting the teeth of cross cut and other saws, and it has for its objectto produce a device of this class which shall possess superioradvantages in point of simplicity, durability and general efliciency,and by the use of which the teeth of a saw may be set with absoluteaccuracy without having recourse to skilled labor.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invent-ion; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theappended claims may be resorted to when desired.

In the drawing: Figure 1 is a perspective view of a device constructedin accordance with the invent-ion, a portion of a saw blade being shownin position for operation. Fig. 2 is a longitudinal sectional view,taken on the line 2--2 in Fig 1. Fig. 3 is a vertical transversesectional view, taken on the line 33 in Fig. 1. Fig. 4 is a sectionaldetail view taken on the line 4-4 in Fig. 1.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The base 1 of the improved device is provided with a longitudinal grooveor recess 2 adjacent to which an upstanding flange 3 is formed orsecured. The base 1 which is adapted to support the saw that is to beoperated upon has a transverse groove 4: in which the anvil block 5 isseated and firmly secured by fastening members 6, such as bolts orrivets. The anvil block which is made of hardened steel or othersuitable material, is flush with the upper face of the base member 1,and is of a length equal to the width of the saw supporting portion ofsaid base member, so as to afiord a firm Specification of LettersPatent.

support for the saw; said anvil block has a beveled face portion 6overhanging the groove or recess 2, the bevel of said face portioncorresponding with the angle at which the saw teeth-are to be set.

The base member 1 is connected with the flange 3 by means of guide rods7 extending transversely of the groove or recess 2 at either side of theanvil block, said rods serving to guide a slidable gage member 8 whichconsists of a block of suitable material having a deep notch 9 toaccommodate the beveled face portion of the anvil block. The upstandingflange 3 has a threaded aperture 10 for the reception of an adjustingscrew 11, the inner end of which has swiveled connection with the guidemember which latter may be moved or adjusted transversely of the grooveor recess 2 by means of the said screw 11.

The beveled face portion of the anvil block is provided with avertically movable punching member consisting of a head 12 having ashank 13 which is guided through apertures in the anvil block and thebase, and which is projected in an upward direction by the action of asuitably arranged flat spring 14- which is seated in a recess 24 in theunderside of the base. The head 12 of the punching member projects abovethe beveled face portion 6 of the anvil block, and the under face ofsaid head portion is parallel to the beveled face portion 6. When theblade 15 of the cross cut or other saw is placed upon the base 1, itwill likewise be firmly supported on the anvil block which extends overthe entire width of the base and the saw teeth may be successivelyintroduced between the beveled faces 6 and 12 of the anvil block and thepunching member, respectively, and by striking the punching member sharpblows with a hammer, it may be actuated to set the teeth at the desiredangle. It is obvious that the gage member 8 may be previously adjustedto be engaged by the points of the saw teeth, thereby serving to holdthe saw blade true, while the teeth are being set. It is also evidentthat the face of the gage member may be either straight or curvedaccording to the nature of the saw that is to be operated upon. Theanvil block and the punching member may be mounted in such a manner asto be readily detached to enable others having opposed faces ofdifi'erent angles to be substituted when desired. By making the anvilblock of a length equal to the Width of the saw supporting portion ofthe base plate, said anvil block afi'ords an extended support for thesaw blade, and it is conveniently accessible when desired to substituteanother anvil block in the place thereof. The punch being guided throughapertures not only in the anvil block, but also in the base plate Willbe held perfectly true to its Work.

Having thus described the invention, What is claimed is:

In a saw setting device, a saw supporting base member having a recess inthe underside thereof and provided in its upper side with a longitudinalrecess, an upstanding flange, and a transverse groove formed in andextending the entire Width of the saw supporting portion of said basemember, an anvil block seated in the transverse groove and having abeveled face portion extending into the longitudinal recess, a springactuated punch member operating through the beveled face portion of theanvil block and having a beveled face portion opposed there to, saidpunch member extending also through the base member and into the recessin the underside of said base member, a flat spring mounted in saidrecess and engaging the lower end of the punch member to force thelatter in an upward direction, guide members connecting the base withthe upstanding flange, a gage member movably supported upon the guidemembers, and an adjusting screw for the gage member operating throughthe upstanding flange.

In testimony whereof I afiiX my signature in presence of two Witnesses.

ALLEN STANLEY HARRIS.
